Abstract
- Efficient organic blue materials are essential to develop highly efficient organic light-emitting diodes. However, there is a challenge to commercialize efficient blue compounds due to the fundamentally wide band gap and the lack of pure blue emitters. In this study, the new anthracene-based fluorescent emitter, (4-(10-(4-(9H-carbazol-9-yl)-2-methylphenyl)anthracen-9-yl)-3-methylphenyl)diphenylphosphine oxide (CZm-AN-mPO) was designed and synthesized. The thermal, photophysical and electrochemical properties of the CZm-AN-mPO were systematically investigated. The CZm-AN-mPO exhibits a deep-blue emission at 425 nm and AIE property with a relatively narrow full-width at half maximum of 34 nm. The CZm-AN-mPO based non-doped devices show pure blue emission. The optimized OLEDs indicated maximum external efficiencies of 4.3% and 4.2% at emission layer thickness of 20 nm and 40 nm, respectively. [ABSTRACT FROM AUTHOR]
